For some reason, probably because build requests are meant to be short lived
and we don't get a lot of bugs about paging misbehavior, when paging instances
with a marker, we didn't raise MarkerNotFound if we didn't find the marker in
the list of build requests. Doing so would match what we do when paging over
cells and listing instances using a marker. Once we find the marker, be that
in build_requests, or one of the cells, we need to set the marker to None to
stop looking for it elsewhere if we have more space to fill our limit.
For example, see change I8a957bebfcecd6ac712103c346e028d80f1ecd7c.
This patch fixes the issue by raising MarkerNotFound from BuildRequestList
get_by_filters if there is a marker and we didn't find a build request for
it. The compute API get_all() method handles that as normal and continues
looking for the marker in one of the cells.
